CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 399,633, dated March12, 1889.

Application filed May 3l, 1888.

To @ZZ whom, it T11/(ty concern:

Be it known that we, FRANK RUPREOHT, a subject otl the Emperor ofGermany, and FRANCIS G. BATES, a citizen of the United States, residing7respectively, at Syracuse, in the county ot Onondaga, State ol New York,and Philadelphia, county ot' Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Car-Heaters, of which thefollowing is a specification.

This invention is designed to he used in connection with pipesconducting steam through railway-cars t'or heating the same; and the ohject ot' the invention is to close the pipe at opposite ends of the carautomatically with the disconnecting of the said car from the train; andto that end our invention consists in the novel construction andcombination, with two sections ot' the car-heater pipe, of a valve-caseinterposed and connected to said sections and valves arranged converselyin relation to each other in the case and held mechanic-ally in closedposition under diiterent degrees of resistance, all hereinatteil morefully described, and specifically set forth in the claims.

In the annexed drawin Figure l is a side elevation ot the end portionsolf two adjacent cars equipped with our invention. Fig. 2 is a detachedenlarged top plan view of the valve-case without its cover and a portionof the interior broken awayto illustrate the form and arrangement ot'the valves and their seats; and Fig. El is a transverse section on line.1' .1', Fig. 2.

Similar letters of reference indicate corresponding parts.

C represents a valve-ease secured to the car in any suitahle position,though preferably under the plattform l) on the end oi' the car, asshown in Fig. il ot' the drawings. Said valve-case is pr i vided at theeenteisol its opposite ends with pipe attachments u a', and isinterposed and connected tothe steam-pipe sections A A', one of whichleads to the radiators in the car, and the other receives steam eitherdirect from the engine connected to the car or from an intervening caror cars. The

other pipe-section, A, connects, as hereinafter described, with asimilar valve-case, O, se

cured to the adjacent car. The interior of the case O is provided atopposite ends with two compartments, C O,1'ormed by a frame, I),extended across the ease and secured in position in any suitable andwell-known manner. i

Longitudinally through the frame D, at op posite side of thelongitudinal central line, are extended channels c c, which thus connectthe two compartments C O, said channels being each formed with avalve-seat, t, at one end and converse to that of the other channel. Inthe channels c c are placed longitudinallymovable valves n y1" disposedreverse in relation to each other, and provided with hearings by whichthey rest on the seats when the valves are in their closed position. TheShanks u. of the valves are formed with spiral iianges c and interveningspiral grooves c', so that the steam can enter the channels c c, and it"under sufcient pressure to lift the valves from their seats the valvesreceive a rotary motion, and thus change their positions on their seats,and thereby cause the same to wear evenly. These valves are held 1neehanically normally in their closed positions under different degrees ofresistance, preferably hy means ot spiral springs d d, held against theclosing ends of the valves hy adjustingscrews l Z, working inscrew-threaded apertures in the end plates of the valve-case O, andprovided at the inside of said case with a collar, l', against which oneend ot' the spring d bears. By means of said screws the tension of thesprings is to he so adjusted that the valve y1f', which has to resistthe hacle pressure of steam from the pipe A leading into t-he car,receives greater pressure from its spring d than the valve which has toresist the pressure. of the steam received from the engine. The eiil'ectof this arrangement of the valves if r is a-s follows Then the carisconnected at opposite ends to a train and the steam is allowed to passtrom the locomotive through the pipe A into the chamber C, the va-lvc twill he forced open by said current-of steam while the spring d holdsthe valve 1" closed, and thus the steam is compelled to pass from thechamber O through the pipe A to the radiators in the ear, and fromthence the (No model.)

IOO

steam passes in the same manner through the cha nber C on the oppositeend of the car and into the radiators in the adjacent car. It will beobserved that this arrangement is adapted to operate with either end ofthe car toward the engine. n n denote drip-faucets for letting the waterof condensation out of the Valve-chamber. The pipe-section A', whichprojects from the end of the valvechaniber C facing from the car, isprovided with a stop-cock, e, by which to cut off the steam completelywhen desired, and to that end of said pipe-section is connected atelescopic pipe-coupling, 71 by which to connect said pipe-section witha pipe projecting' from a valve-case, C, connected to the end of theadjacent car.

Having described our invention, what We claim as new, and desire tosecure by Letters Patent, isv l. In combination with two sections of acar steam-heater pipe, a valve-case interposed and connected at oppositeends to said sections and valves arranged conversely in relation to eachother in the case and held mechanically in closed positions underdiffer- 3. In combination with the pipe-sections A A', the case C,provided with the pipe attach* ments a d at the centers of its ends, andhaving thereat the compartments C C', intervening longitudinal channelsc c, connecting said compartments at opposite sides of the longitudinalcentral line of the case, and each provided with a valve-seat reversefrom that of the other, valves n fu', .movable in said channels andclosing against the aforesaid seats, and springs (l d, adjustable intension and pressing the valves onto their seats, substantially asdescribed and shown.

4. In combination with the pipe-sections A A, the case C, interposed andconnected to said pipesections, compartments C C in opposite ends of thecase, longitudinal channels c c, connecting the compartments,reverselydisposed valves t' o in said channels, springs d d, holding thevalves in their closed position, the stop-cock e, connected to thepipe-section A', and the telescopic coupling h on said pipesection,substantially as described and shown,

In testimony whereof We have hereunto signed our naines, in the presenceof two witnesses, at Syracuse, in the county of Onondaga, in the Stateof New York, this 26th day of May, 1888.
